2020 Map of Sliderock Ridge

About this map

The Middle Fork Salmon Wild and Scenic River carves a deep path through the central portion of this map, serving as the primary drainage for a network of steep canyons and alpine creeks. This area is defined by its administrative and natural division between the Boise National Forest and the Challis National Forest. Backcountry access is marked by remote airstrips such as the Cougar Ranch Airport and the Mahoney Creek USFS Airport, highlighting the region's reliance on aerial transport for remote ranching and forest management. Along the river, features like Sunflower Hot Springs and Jackass Flat indicate traditional points of interest for river travelers. The landscape is dominated by high divides including Sliderock Ridge and Sheep Mtn Ridge, while the headwaters of Little Loon Cr and Sunflower Cr flow through complex terrain marked by landmarks like Jackass Gulch.
